| Igama lomkhiqizo | 0Cr23Ni13 (309S), 0Cr25Ni20 (310S), 0-1Cr25Ni20Si2,0-1Cr20Ni14Si2, S30815 (253MA), njll.; |
| Ukucaciswa komkhiqizo | Ubukhulu: 0.5 ~ 80mm; |
| Ukusetshenziswa komkhiqizo | Isetshenziswa kakhulu ku-boiler, amandla (amandla enyukliya, amandla ashisayo, i-fuel cell), isithando somlilo sezimboni, isishisi, isithando sokushisa, amakhemikhali, i-petrochemical kanye nezinye izinkambu ezibalulekile; |
| Izici zomkhiqizo | Izithako ezinengqondo, ukumelana nokushisa okuhle, ukumelana nokugqwala okuqinile, kube ukukhetha kokuqala kwabasebenzisi bomkhiqizo abaziwayo ekhaya naphesheya; |
| Ukusebenza komkhiqizo | Ukusebenzisa insimbi encibilikisiwe njengempahla eluhlaza, ukucwengisiswa kwevacuum, izakhi zokufakwa eziyingozi, okuqukethwe kwegesi ephansi, ukuhlanzeka kwensimbi ephezulu, ukusebenza kahle kokushisela; umthamo omkhulu wesithando somlilo, isilinganiso esikhulu sokucindezela, ukwakheka kwamakhemikhali okufaniswayo nokuzinzile, ukusebenza kahle kokunwetshwa; |
| Amandla emakethe yomkhiqizo | Ngokuthuthuka okusheshayo komnotho waseShayina, imboni yamandla enuzi ikhula ngokushesha, kanti nokusetshenziswa kwensimbi engagqwali engashisi nakho kuyanda. Ukuthuthukiswa okusheshayo kwesithando somlilo sezimboni, i-reactor yamakhemikhali, i-incinerator nezinye izimboni kukhuthaze ukukhula okusheshayo kwesidingo sensimbi engagqwali engashi. Isidingo esikhethekile sensimbi engagqwali engashisi embonini yesiteshi samandla kabhoyela senza isidingo sensimbi engagqwali esezingeni eliphezulu sibe sikhulu futhi sibe sikhulu. |
Ukwakheka kanye ne-alloying Elements: Amapuleti ensimbi engagqwali angashisi ngokuvamile enziwa ngama-alloys anokuqukethwe kwe-chromium ephezulu, njengoba i-chromium idlulisela ukumelana ne-oxidation nokugqwala emazingeni okushisa aphakeme. Ezinye izakhi ze-alloying ezifana ne-nickel, i-molybdenum, futhi ngezinye izikhathi i-titanium noma i-niobium ingase yengezwe ukuze kuthuthukiswe izici ezithile ezifana nokumelana nokukhasa kanye namandla emazingeni okushisa aphezulu.
Amamaki ensimbi engagqwali ajwayelekile angashisi ahlanganisa:
I-Austenitic Stainless Steels: Amabanga afana ne-310S kanye ne-321 ayizinsimbi ezingenasici ze-austenitic ezinokuqukethwe okuphezulu kwe-chromium ne-nickel, ezinikeza ukumelana okuhle kakhulu ne-oxidation kanye nokugqwala ezindaweni ezinezinga lokushisa eliphezulu.
Izinsimbi Ezingenasici ze-Ferritic: Amabanga e-Ferritic afana no-409 no-430 asetshenziswa ezinhlelweni lapho kudingeka ukumelana nokushisa okusesilinganisweni, futhi anikeza ukumelana nokugqwala okuhle ezindaweni ezithile.
I-Martensitic Stainless Steels: Amabanga e-Martensitic afana no-410 no-420 anikeza amandla aphezulu nokumelana nokushisa okumaphakathi. Zivame ukusetshenziswa ezinhlelweni ezidinga ubulukhuni nokumelana nokugqwala emazingeni okushisa aphakeme.
Izinhlelo Zezinga Lokushisa Eziphezulu: Amapuleti ensimbi engagqwali angashi asetshenziswa ezinhlelweni ezihlukahlukene zokushisa okuphezulu, okuhlanganisa:
Imboni ye-Petrochemical: Lawa mapuleti asetshenziswa ekwakhiweni kwemishini ye-petrochemical efana nezithando zomlilo, ama-reactors, nezishintshisi zokushisa lapho ukumelana namagesi abolayo namazinga okushisa aphezulu kubalulekile.
Ukukhiqiza Amandla: Amapuleti ensimbi eqinile angashisi athola ukusetshenziswa ezitshalweni zikagesi zezingxenye ezifana namabhayela, amapayipi esitimu, nama- turbine blades, lapho kufanele amelane nezinga lokushisa eliphezulu nezingcindezi ezihlobene nokukhiqizwa kwamandla.
I-Aerospace: Ezinhlelweni ze-aerospace, lawa mapuleti asetshenziswa ezingxenyeni ezifana nesistimu yokukhipha umoya, izingxenye zenjini, nezihlangu zokushisa lapho ukuchayeka emazingeni okushisa aphezulu phakathi nokusebenza kuvame.
Izinqubo Zokukhiqiza: Izimboni ezibandakanyeka ezinqubweni zokukhiqiza ezifana nokwelashwa kokushisa, ukukhiqizwa kwengilazi, nokusebenza kwensimbi zisebenzisa amapuleti ensimbi engagqwali angashisi amathuluzi nezinto ezivezwe ekushiseni okukhulu.
Izakhiwo:
Ukumelana ne-Oxidation: Amapuleti ensimbi engagqwali angashi aklanyelwe ukumelana ne-oxidation emazingeni okushisa aphezulu, enze isendlalelo se-oxide esivikelayo endaweni evimbela ukuwohloka okwengeziwe.
I-Creep Resistance: Ikhono lezinto ezibonakalayo ukumelana nokuchayeka isikhathi eside emazingeni okushisa aphezulu kanye nengcindezi eqhubekayo ngaphandle kokuguga ngokweqile kwaziwa ngokuthi ukumelana ne-creep. Lesi sakhiwo sibalulekile ekusetshenzisweni okubandakanya amazinga okushisa aqhubekayo.
Ukumelana Nokugqwala: Amapuleti ensimbi engagqwali angashisi abonisa ukumelana nokugqwala okuhle kakhulu ezindaweni ezinolaka, avikela okokusebenza ekonakalisweni okubangelwa amagesi aqala ukugqwala noma uketshezi.
Amandla emazingeni okushisa aphezulu: Ama-alloys asetshenziswa kulawa mapuleti akhiwe ukuze alondoloze amandla abo emishini nobuqotho ngisho namazinga okushisa aphakeme, okuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo ezinzima.
Isiphetho: Amapuleti ensimbi engagqwali angashisi adlala indima ebalulekile ezimbonini ezidinga izinto ezikwazi ukumelana nezinga lokushisa elidlulele kanye nezindawo ezibolayo. Inhlanganisela yabo eyingqayizivele yokwakheka kwe-alloy kanye nezinqubo ezikhethekile zokukhiqiza kubenza babaluleke kakhulu ekusetshenzisweni lapho izinto ezivamile zingase zinganikezi ukuqina nokuphila isikhathi eside okudingekayo. Njengoba ubuchwepheshe buthuthuka, ukuthuthukiswa kwezingxube ezintsha zensimbi engagqwali ezingashisi kuyaqhubeka nokwandisa ububanzi bokusebenza kwazo ezindaweni ezihlukahlukene ezisezingeni eliphezulu.
